BOILER CLEANER Claims.

My invention has relation toimprovernents in boiler cleaners and itconsists in the novel features:ofconstruction morefully set forth in thespecification and pointed out in the claims.

The present invention is concerned more particularly with the means forsupporting the operating head of the boiler cleaner rather than theconstruction of the head itself. The principal object of the inventionis to support the boiler cleaner from the tubes of the boiler instead offrom the boiler wall so that the boiler cleaner will be carried with thetubes during the expansion and contraction thereof and so thecontraction and expansion of the boiler wall will in nowise effect theboiler cleaner which passes freely through said wall.

A further object of the invention is to provide a support for boilercleaners for carrying the vweight of the operating head irrespective ofthe construction thereof so that the supporting means may be applied toany type of boiler cleaner.

Other objects of the invention and advantages inherent therein will bebetter apparent from a detailed description of the same in connectionwith the accompanying drawing, in which:

Figure 1 is a vertical cross-section through a portion of the boilerwall and the first two boiler tubes adjacent thereto showing my improvedboiler cleaner support and the boiler cleaner carried thereby, saidboiler cleaner being shown in elevation; Fig. 2 is a vertical,transverse section taken on the line 2-2 of Fig. 1; and Fig. 3 is avertical, cross-section taken on the line 3-3 of Fig. l with the boilercleaner support and boiler tubes carrying the same shown in elevation.

Referring to the drawing, W represents the boiler wall and T representsadjacent tubes of the boiler on which is secured my improved boilersupport S for the boiler cleaner operating head H. The operating head Hforms no part of the present invention except that the supportingbracket I for the operating head is provided with a ring 2 having anexternal channel 3 for receiving a saddle 4, which is a part of theboiler cleaner support, as will be more fully described hereinafter.

In the present invention the support S is anchored to the boiler tubesT, said support comprising a tubular member 5, the outer enlarged end 6of which is provided with internal threads l and a rib 8 extendingdownwardly and inwardly from the bottom of the tubular portion 5, whichrib terminates in a heel 9 of (Cl. m-392)' arcuate formation forabutment againstone of thev tubes T. Disposedzbelow anditransversely, ofthe tubular portioni51.- is: aasemiecylindrficaly socket. .Ii'forreceiving.-one .of theaboilertubes T on which the support is clamped bymeans of the clamp members II, II which embrace the tube T and aresecured in spaced relation to the lateral flanges I2, I2 and I3, I3extending laterally from the socket I0. The clamp members II, II arealso provided with flanges I4, I4 through which bolts I5, I5 pass forfastening the clamp members to the socket member whereby the tube T isfirmly clamped. The supporting member S projects into an opening Oprovided in the boiler wall W in which opening is tted a wall sleeve I6of rectangular crosssection. The wall sleeve I6 is provided with aflange II fitting against the outer surface of the boiler wall andsuitable bolts I8 pass through said flange to secure the wall sleeve inplace.

Formed within the wall sleeve I6 is an annular flange I9 through whichpasses a tube 2U, the inner end of which is screw-threaded into theenlarged end 6 of the tubular member 5. The outer end of the tubecarries a bracket 2I which has a bearing portion 22 traversed by thetube 20 and an outwardly projecting shelf 23 which carries the saddle 4.A set-screw 24 passes through the bearing portion 22 to firmly securethe bracket 2i and tube 20 together. A pair of oppositely disposed lugs25, 25 project downwardly from the saddle 4 so as to provide a channel26 between them, which channel receives the shelf 23A to which thesaddle is secured by means of set-screws 2l, 2'I. The bracket 2l haslateral enlargements 28, 28 provided with threaded openings 29, 29 toreceive set-screws 3D, 30 for adjusting the position of the bracket, andlock-nuts 3l, 3| are provided to hold the studs in their adjustedposition.

An abutment plate 32 is mounted on tube 20 in abutting relation with thebearing 22 and a sealing plate 33 is also mounted on the tube 2B inabutting relation with the inwardly turned end I9 of flange I9, thesealing plate 33 being held in intimate relation with the ange I9 by acoiled spring 34. The purpose of the sealing plate 33 is to maintain theopening in the flange I9 tightly closed, irrespective of movements ofthe tube 20 relative to the boiler wall W, it being understood that thetube 20 being a part of the boiler cleaner, is carried by and moves withthe boiler tubes.

The bracket 2| serves to directly support the head H of the boilercleaner and is maintained in xed position by its abutting relationagainst ilange Il of the wall sleeve I6, and the tubular member 5 servesto anchor the bracket 2| on the boiler tubes T. Thus the entire boilercleaner support S bears against the boiler wall and is anchored to theboiler tubes T.

Having described by invention, I claim:

1. In combination with a boiler cleaner adapted to traverse an openingin the boiler Wall, a support for the boiler cleaner comprising ananchor member mounted on the boiler tubes, an abutment member connectedthereto and abutting against the outer surface of the boiler Wall, andan adiustable saddle mounted on the abutment member, said boiler cleanerresting on the saddle.

2. In combination with a boiler cleaner for removing deposits from thetubes of boilers, a support for the boiler cleaner bearing against theboiler wall and anchored to the boiler tubes, said support including atubular member clamped against one of the boiler tubes and bracedagainst another of said tubes.

3. In combination with a boiler cleaner for removing deposits from thetubes of boilers, a 'support for the boiler cleaner anchored to theboiler tubes, said support including a bracket abutting against theboiler Wall, and means for adjusting the spacing of said bracket fromthe Wall.

4. In combination with a boiler cleaner comprising a blower tube and anoperating head therefor, a support for the boiler cleaner comprising atubular member traversed by the boiler cleaner, said tubular memberincluding means for securing the same to the boiler tubes,- and anabutment member carrying the boiler cleaner head, said abutment memberbeing xed to the tubular member and having abutment; against the outersurface of the boiler wall.

5. In combination with a boiler cleaner for removing deposits from thetubes of boilers, a support for the boiler cleaner, said supportincluding a member clamped against one of the boiler tubes and bracedagainst another of said tubes.
